Definitions
- Flossing of teeth is an important part of oral hygiene. Flossing removes plaque and debris from interdental areas in an oral cavity.
- Conventional devices for flossing comprise a dental floss in a frame that is used to floss teeth including the back teeth in the oral cavity, where a rear end of the frame is used as a toothpick.
- conventional devices for flossing teeth dislodge the plaque and the debris from the interdental areas, they do not brush away the dislodged plaque and debris.
- interdental brushes are required for cleaning the interdental areas.
- the interdental brushes do not clean contact areas between the teeth as thoroughly as dental floss.
- each tooth and the space between adjacent teeth also limit the application of interdental brushes in cleaning the contact areas between the teeth.
- the space between adjacent teeth is called an embrasure.
- the embrasure facing the buccal side of the teeth is wide and thick, while the embrasure facing the lingual side of the teeth is narrow and thin.
- Interdental brushes and dental floss have a uniform geometry that does not facilitate the cleaning of contact areas between adjacent teeth due to the difference in the embrasures at the buccal side and the lingual side of the teeth.
- the dental floss and brush apparatus disclosed herein addresses the above stated needs for allowing a user to perform a combination of flossing and brushing actions for enhanced cleaning of interdental areas in an oral cavity.
- the dental floss and brush apparatus disclosed herein comprises a handle, an arcuate head member, and an interdental cleaning member.

Abstract
A dental floss and brush apparatus includes a handle, an arcuate head member including a first arcuate arm and a second arcuate arm, a flossing assembly, and an interdental cleaning member including a flossing element and brush bristles. The flossing assembly includes an elongate channel to accommodate and allow traversal of the flossing element, and a spool member to wind and rotate the flossing element for the traversal of the flossing element through the elongate channel. The flossing element supported between two tubular members dislodges interdental substances in an oral cavity. The brush bristles create a diverging extension arm of a wide dimension towards the first arcuate arm to brush away the dislodged interdental substances from a buccal side of teeth, and another diverging extension arm of a narrow dimension towards the second arcuate arm to brush away the dislodged interdental substances from a lingual side of the teeth.
Description
- This application claims priority to and the benefit of provisional patent application No. 61/834,421 titled “Dental Floss And Brush Apparatus”, filed in the United States Patent and Trademark Office on Jun. 13, 2013. The specification of the above referenced patent application is incorporated herein by reference in its entirety.
- Flossing of teeth is an important part of oral hygiene. Flossing removes plaque and debris from interdental areas in an oral cavity. Conventional devices for flossing comprise a dental floss in a frame that is used to floss teeth including the back teeth in the oral cavity, where a rear end of the frame is used as a toothpick. Although conventional devices for flossing teeth dislodge the plaque and the debris from the interdental areas, they do not brush away the dislodged plaque and debris. In some cases, for example, where the spacing between the teeth of the user is larger than normal, interdental brushes are required for cleaning the interdental areas. However, the interdental brushes do not clean contact areas between the teeth as thoroughly as dental floss. The shape of each tooth and the space between adjacent teeth also limit the application of interdental brushes in cleaning the contact areas between the teeth. The space between adjacent teeth is called an embrasure. The embrasure facing the buccal side of the teeth is wide and thick, while the embrasure facing the lingual side of the teeth is narrow and thin. Interdental brushes and dental floss have a uniform geometry that does not facilitate the cleaning of contact areas between adjacent teeth due to the difference in the embrasures at the buccal side and the lingual side of the teeth.
- Hence, there is a long felt but unresolved need for a combination dental floss and brush apparatus that allows a user to perform a combination of flossing and brushing actions for enhanced cleaning of interdental areas in an oral cavity, and that cleans contact areas between adjacent teeth at the buccal side and the lingual side of the teeth.
- This summary is provided to introduce a selection of concepts in a simplified form that are further disclosed in the detailed description of the invention. This summary is not intended to identify key or essential inventive concepts of the claimed subject matter, nor is it intended for determining the scope of the claimed subject matter.
- The dental floss and brush apparatus disclosed herein addresses the above stated needs for allowing a user to perform a combination of flossing and brushing actions for enhanced cleaning of interdental areas in an oral cavity. The dental floss and brush apparatus disclosed herein comprises a handle, an arcuate head member, and an interdental cleaning member. The arcuate head member is rigidly connected to an upper end of the handle. The arcuate head member comprises arcuate arms configured to define a generally arcuate opening. The interdental cleaning member allows cleaning of interdental areas in the oral cavity. The interdental cleaning member is rigidly connected to the arcuate arms of the arcuate head member across the arcuate opening. The interdental cleaning member comprises one or more filament strands configured to create a flossing element at about a mid-section of the filament strands, and to create filament arms extending in opposing directions from the mid-section of the filament strands to the arcuate arms of the arcuate head member. The flossing element dislodges interdental substances, for example, plaque, debris such as food deposits, etc., that accumulate between the teeth or interdental areas in an oral cavity. In an embodiment, the interdental cleaning member further comprises multiple brush bristles fixedly attached at predetermined positions on the filament arms of one filament strand or multiple filament strands. The brush bristles brush away the dislodged interdental substances from the interdental areas in the oral cavity without abrading the interdental areas.
- In an embodiment, the dental floss and brush apparatus comprises a handle, an arcuate head member, a flossing assembly, and an interdental cleaning member. In this embodiment, the dental floss and brush apparatus cleans contact areas between adjacent teeth at a buccal side and a lingual side of the teeth. The arcuate head member is rigidly connected to an upper end of the handle. The arcuate head member comprises a first arcuate arm and a second arcuate arm configured to define a generally arcuate opening. The flossing assembly comprises an elongate channel, a first tubular member, a second tubular member, and a spool member. The elongate channel is internally bored proximal to a periphery of the handle and extends from a first opening positioned at a distal end of the first arcuate arm of the arcuate head member to a second opening positioned at a distal end of the second arcuate arm of the arcuate head member. The elongate channel accommodates and allows a flossing element to traverse the elongate channel. The first tubular member and the second tubular member of the flossing assembly are axially connected to the first opening in the first arcuate arm and the second opening in the second arcuate arm respectively. The first tubular member and the second tubular member house the flossing element for allowing the flossing element to traverse across the arcuate opening from the first opening to the second opening. The spool member is internally positioned proximal to a lower end of the handle. The spool member winds the flossing element around a circumference of the spool member and rotates about a spooling axis for allowing the flossing element to traverse through the elongate channel from the circumference of the spool member to the first opening in the first arcuate arm of the arcuate head member, and then through the first opening and across the arcuate opening to the second opening in the second arcuate arm of the arcuate head member, and subsequently from the second opening to a section of the spool member protruding outside the handle.
- The interdental cleaning member is connected to the first arcuate arm and the second arcuate arm of the arcuate head member across the arcuate opening. The interdental cleaning member of this embodiment of the dental floss and brush apparatus comprises the flossing element. The flossing element traverses from the first opening to the second opening across the arcuate opening via the flossing assembly. The flossing element supported between the first tubular member and the second tubular member is configured to dislodge interdental substances in interdental areas in an oral cavity. In this embodiment of the dental floss and brush apparatus, the interdental cleaning member further comprises brush bristles of varying lengths fixedly attached at predetermined positions on the first tubular member and the second tubular member of the flossing assembly. The brush bristles create a diverging extension arm towards each of the first arcuate arm and the second arcuate arm of the arcuate head member. The diverging extension arm towards the first arcuate arm of the arcuate head member is of a generally wide dimension and is configured to brush away the dislodged interdental substances from the buccal side of the teeth without abrading interdental areas in the oral cavity. Similarly, the diverging extension arm towards the second arcuate arm of the arcuate head member is of a generally narrow dimension and is configured to brush away the dislodged interdental substances from the lingual side of the teeth without abrading the interdental areas in the oral cavity.
